[Docket No. 95-CE-55-AD; Amendment 39-9837; AD 96-24-13]
RIN 2120-AA64


Airworthiness Directives; The New Piper Aircraft, Inc. (Formerly 
Piper Aircraft Corporation) PA-31, PA-31P, and PA-31T Series Airplanes

AGENCY: Federal Aviation Administration, DOT.

ACTION: Final rule.

-----------------------------------------------------------------------

SUMMARY: This document supersedes AD 75-26-18, which currently requires 
modifying the landing gear selector cable forward attachment pin 
assembly by installing a safety lock wire on certain The New Piper 
Aircraft Inc., (Piper) PA-31, PA-31P, and PA-31T series airplanes. The 
action will require the same action as AD 75-26-18. An incorrect 
designation of Piper Model PA-31 airplanes as Piper Model PA-31-310 
airplanes in AD 75-26-18 prompted the proposed AD action. The actions 
specified by this AD are intended to prevent the landing gear selector 
cable forward attachment pin assembly from becoming separated from the 
powerpack control arm, which, if not corrected, could cause loss of 
landing gear retraction or extension.

DATES: Effective January 17, 1997.
    The incorporation by reference of certain publications listed in 
the regulations is approved by the Director of the Federal Register as 
of January 17, 1997.

SUPPLEMENTARY INFORMATION:

Events Leading to This Action

    A proposal to amend part 39 of the Federal Aviation Regulations (14 
CFR part 39) to include an AD that would apply to Piper PA-31, PA-31P, 
and PA-31T series airplanes was published in the Federal Register on 
April 29, 1996 (61 FR 18697). This action would supersede AD 75-26-18 
with a new AD that would retain the same requirements as AD 75-26-18 
and change the model designation in the Applicability section from 
Piper Model PA-31-310 airplanes to Piper Model PA-31 airplanes. With 
this in mind, the proposed action would not provide any additional cost 
impact upon U.S. operators over that already required by AD 75-26-18.

Related Service Information

    Accomplishment of this action will be in accordance with Piper 
Service Bulletin (SB) No. 488, dated October 24, 1975.
    Interested persons have been afforded an opportunity to participate 
in the making of this amendment. No comments were received on the 
proposed rule or the FAA's determination of the cost to the public.

FAA's Determination

    After careful review of all available information related to the 
subject presented above, the FAA has determined that air safety and the 
public interest require the adoption of the rule as proposed except for 
minor editorial corrections. The FAA has determined that these minor 
corrections will not change the meaning of the AD and will not add any 
additional burden upon the public than was already proposed.

Regulatory Impact

    The regulations adopted herein will not have substantial direct 
effects on the States, on the relationship between the national 
government and the States, or on the distribution of power and 
responsibilities among the various levels of government. Therefore, in 
accordance with Executive Order 12612, it is determined that this final 
rule does not have sufficient federalism implications to warrant the 
preparation of a Federalism Assessment.
    For the reasons discussed above, I certify that this action (1) is 
not a ``significant regulatory action'' under Executive Order 12866; 
(2) is not a ``significant rule'' under DOT Regulatory Policies and 
Procedures (44 FR 11034, February 26, 1979); and (3) will not have a 
significant economic impact, positive or negative, on a substantial 
number of small entities under the criteria of the Regulatory 
Flexibility Act. A copy of the final evaluation prepared for this 
action is contained in the Rules Docket. A copy of it may be obtained 
by contacting the Rules Docket at the location provided under the 
caption ADDRESSES.

altered, or repaired so that the performance of the requirements of 
this AD is affected, the owner/operator must request approval for an 
alternative method of compliance in accordance with paragraph (c) of 
this AD. The request should include an assessment of the effect of 
the modification, alteration, or repair on the unsafe condition 
addressed by this AD; and, if the unsafe condition has not been 
eliminated, the request should include specific proposed actions to 
address it.
    Compliance: Required within 50 hours time-in-service (TIS) after 
February 9, 1976 (effective date of AD 75-26-18) or within the next 
25 hours TIS after the effective date of this AD, whichever occurs 
later, unless already accomplished.

pin assembly by installing a safety lock wire in accordance with the

compliance time that provides an equivalent level of safety may be 
approved by the Manager, FAA, Atlanta Aircraft Certification Office, 
Campus Building, 1701 Columbia Avenue, suite 2-160, College Park, 
Georgia 30337-2748. The request shall be forwarded through an 
appropriate FAA Maintenance Inspector, who may add comments and then
